STMicroelectronics L4931CDT35-TR Low Dropout Voltage Regulator

The L4931CDT35-TR is a high-performance, low dropout voltage regulator designed by STMicroelectronics, a leader in the semiconductor industry. This component is specifically engineered to provide a stable and reliable power supply, making it an ideal choice for sensitive electronic applications where voltage precision is critical. With its low dropout performance, the L4931CDT35-TR ensures efficient operation even when the input voltage is close to the output voltage, minimizing power loss and improving overall system efficiency.

Featuring a fixed output voltage of 3.5V, the L4931CDT35-TR can deliver up to 250mA of output current, which is suitable for low-power devices such as microcontrollers, sensors, and analog circuits. The regulator boasts exceptional accuracy with a tight output voltage tolerance, ensuring that the connected components receive a consistent power supply without fluctuations that could potentially cause malfunctions or damage.

One of the standout features of the L4931CDT35-TR is its low quiescent current, which makes it particularly well-suited for battery-powered applications where power conservation is paramount. This characteristic extends battery life and reduces the need for frequent charging or replacement, which is beneficial for portable and remote devices.

The thermal protection feature of the L4931CDT35-TR safeguards the device against overheating. In the event that the internal temperature exceeds safe operating limits, the thermal protection circuitry will automatically shut down the regulator to prevent thermal runaway and potential damage to the device and the system it powers. Additionally, the regulator includes current limiting features to protect against short-circuit and overcurrent conditions, further enhancing its reliability and safety.

Available in a DPAK package, the L4931CDT35-TR is designed for surface-mount technology (SMT), allowing for compact and efficient PCB designs. Its rugged construction ensures that it can withstand the rigors of industrial environments, while its compliance with RoHS directives makes it an environmentally friendly choice for eco-conscious manufacturers.

Overall, the L4931CDT35-TR from STMicroelectronics is a versatile and robust voltage regulator that offers precise voltage regulation, low power consumption, and high reliability, making it an excellent choice for a wide range of electronic applications.
